迄今为止，碳质材料的拉曼光谱研究主要致力于地质和工业材料。另一方面，从艺术文献中得知，根据艺术家的喜好，在不同的地点和时间生产和使用了许多品种的碳基黑色颜料。拉曼光谱分析小至 1 μm 颗粒的能力及其非破坏性使其成为颜料研究的理想工具。无论如何，不同类型碳基黑色颜料的区分受到多方面的影响，其中之一是缺乏参考光谱以及具体的命名法。本文通过拉曼光谱对参考物质进行了研究，以提供参考光谱。所有颜料都显示出两个宽带碳，但有时需要特定的激发条件才能记录高质量的拉曼光谱。根据颜料的特性（天然或人工来源；与所用原材料或生产过程相关的结构影响等），讨论所获得的拉曼特征。因此，根据绘画材料的拉曼光谱，可以进一步了解艺术品中碳基黑色颜料的类型。版权所有 (c) 2015 约翰·威利父子有限公司
Raman spectroscopic studies of carbonaceous materials are, until now, mainly devoted to geological and industrial materials. On the other hand, it is known from artistic literature that many varieties of carbon-based black pigments were produced and used in different places and times, and according to the artist's preferences. The ability of Raman spectroscopy to analyse particles down to 1 mu m and its non-destructiveness make it an ideal tool for pigments investigation. Anyway, the discrimination among different types of carbon-based black pigments is affected by various aspects, one of which is the lack of reference spectra as well as of specific nomenclature. In this paper, reference materials have been studied by means of Raman spectroscopy to provide reference spectra. All the pigments showed two broad bands of carbon, but sometimes specific excitation conditions were required to record a good quality Raman spectrum. The obtained Raman signatures are discussed, on the basis of the specificities of the pigment (natural or artificial origin; structural implications related to the raw materials used or to production processes; etc.). Therefore, on the basis of the Raman spectra of painting materials, further knowledge can be obtained on the type of carbon-based black pigments in works of art.
